      This sample demonstrates the PolylineLinkingTool, which replaces the standard LinkingTool. The tool is defined in its own
      file, as <a href="PolylineLinkingTool.ts">PolylineLinkingTool.ts</a>.
    </p>
    <p>
      The user starts drawing a new link from a node in the normal manner, by dragging from a port, which for feedback purposes
      has a "pointer" cursor. Normally the user would have to release the mouse near the target port/node. However with the
      PolylineLinkingTool the user may click at various points to cause the new link to be routed along those points. Clicking
      on the target port completes the new link. Press <b>Escape</b> to cancel, or <b>Z</b> to remove the last point.
    </p>
    <p>
      Furthermore, because <a>Link.resegmentable</a> is true, the user can easily add or remove segments from the route of
      a selected link. To insert a segment, the user can start dragging the small diamond resegmenting handle. To remove
      a segment, the user needs to move a regular reshaping handle to cause the adjacent two segments to be in a straight
      line.
    </p>
    <p>
      The PolylineLinkingTool also works with orthogonally routed links. To demonstrate this, uncomment the two lines that initialize
      <a>Link.routing</a> to be <a>Link.Orthogonal</a>.
